Software Engineer, Security

WHY HARVEY At Harvey, we’re transforming how legal and professional services operate. By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come. This is a rare chance to help build a generational company at a true inflection point. We have strong product-market fit and world-class investor support. We’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth — personal, professional, and financial — is unmatched. Our team moves fast, takes ownership, and is deeply committed to the mission — operating with intensity, staying close to our customers, and pushing each other for excellence. We live by three values: Decisiveness, Simplicity, and Job's Not Finished. We act quickly on clear judgment over perfect information, we believe simplicity is what scales, and we're never satisfied with where we are. If you want to do the best work of your career alongside people who share that drive, we'd love to build with you. At Harvey, the future of professional services is being written today — and we’re just getting started. ROLE OVERVIEW As a Software Engineer on the Security Engineering team at Harvey, you'll build and operate foundational security services for both our customer-facing product and the internal systems our workforce depends on: encryption and key management, public key infrastructure (PKI), secrets management, and shared controls for identity, secure software delivery, and agent execution. You'll turn security needs into production systems and own the reliability and security of what you build, working closely with engineers and partner teams along the way. Attackers increasingly operate at agent speed, so we’re building defenses that can keep pace. Security at Harvey is an engineering discipline, not a gatekeeper function. We build platforms and libraries that make it hard for engineers to get security wrong, and we measure ourselves on adoption and outcomes rather than tickets filed. Our program is informed by risk: we invest where the actual exposure to our most sensitive data and resources is greatest, rather than where a framework tells us to. WHAT YOU'LL DO - Build and operate services for encryption, key management, and secure storage across product and infrastructure systems, working closely with partner teams - Implement and improve PKI and secrets management workflows, including certificate renewal, secure credential delivery, rotation, and revocation - Build identity controls, sandboxes, and safety harnesses that let services and AI agents operate with least privilege, constrained actions, clear auditability, and effective monitoring - Create secure-by-default libraries and self-service tooling that make encryption, secrets handling, and other shared security controls easy to adopt - Build code, dependency, and secret scanning…
